UPDATE so someone actually made this happen with their own lingq plugin LingQ Addon: AI Tools & Custom Layouts for an Enhanced Learning Experience - #267 by vet8t6z79pc4
Its just as i described. The ability to import your own video without storing any data on to lingQ while still getting watch time and coins. Im hoping to see this functionality in the actual site one day since its already been proven that it can be done. The only thing i would like to see improved is to also have the new video player from android with local videos as well so that all of the attention can be put on the video itself while you learn
